This AquaTech O-Ring Set contains all of the user replaceable O-Rings for the AquaTech Delphin Water Housings. The replacement O-Ring kit contains the rear main O-Ring and a Port-Based Compression Seal O-Ring which is for the front of the Water Housing.

Manufactured to the precision tolerances required to hold a pressure seal on your housing and made of silicon material, it provides the means by which a watertight seal is formed. Silicon O-rings are easy to maintain. It is important to keep them free of dirt and sand, but O-Ring grease is not required.
